Plot of the intensity ratio (1338 nm/I333 nm) from pyrene emission spectra versus the logarithm of the concentration (Log C) of (A) HA-PBCA and (B) HA-PBCA/TPGS at pH 7.4.

Notes: The CAC value was determined as the point of intersection of two tangents drawn to the curve at high and low concentrations, respectively.

Abbreviations: CAC, critical aggregation concentration; HA-PBCA, hyaluronic acid-poly (butyl cyanoacrylate); TPGS, D-alpha-tocopheryl polyethylene glycol 1000 succinate.
